# hMailServer 6.2.7: file pickers and one-click DKIM in the Control Panel

6.2.7 was a Control Panel usability release. The server core was unchanged since 6.2.6, so nothing in message handling moved. Every change sat in the .NET 8 administration Control Panel, closing the gaps that still forced hand-typed paths, external tools or guesswork.

What it changed:

- **File and folder pickers everywhere.** Every field holding a file-system path gained a browse button: the backup destination and restore file, the archive folder, the ACME certificate folder, the OAuth2 public key, the REST API / Web Services TLS certificate and key files, the ClamWin executable and database folder, and the DKIM private key.
- **One-click DKIM.** Domain > DKIM gained Generate key pair. It creates an RSA-2048 key, saves the private key, fills in the path, and shows the exact `selector._domainkey` DNS TXT record (`v=DKIM1; k=rsa; p=…`) with a Copy button. No more running OpenSSL by hand.
- **Passwords.** All password boxes got a reveal toggle. The account editor and the quick-create form got a Generate strong password button, using a cryptographic RNG and copying to the clipboard. The external POP3 fetch-account password is masked rather than shown in clear text.
- **Inputs.** The auto-reply expiry became a date picker. Numeric server settings and the collection editors use up/down number boxes. Every editor dialog obeys Enter to save and Esc to cancel. MX query and Diagnostics output got a Copy button.
- **Window state.** The main window remembers its size, position and maximized state between sessions, and a save-confirmation toast appears after saving.

Because the core was untouched, the regression suite result carried over from 6.2.6: 898 of 898 tests passing, zero failures, zero inconclusive, including live SpamAssassin, ClamAV with real EICAR detection, DMARC evaluation against live DNS, and TLS 1.2/1.3 handshakes end to end.

One package shipped, hMailServer-6.2.7-x64.exe, 64-bit Windows only.
